Fortified plant-based milks are delicious and contain all the calcium, protein, and vitamin D of dairy products but with none of the cholesterol, lactose, hormones, or cruelty found in cow's milk.

Ninety-five percent of the eggs produced in America come from factory-farmed birds. Even if free-range farms were hugely more humane, the sheer number of animals raised to satisfy people's desire for eggs, meat, and milk makes it impossible for us to raise them all on small, free-range farms.

Perhaps one of the most important things you can do for human beings is wean them off an animal-based diet. It hardens the arteries and runs up our health-care costs. The last thing a poor person can afford is a heart attack or cancer or a stroke. And that's all linked to a meat-based diet. I think animal liberation is human liberation.

We are complete press sluts.

Since we can't count on the meat, egg, and dairy industries to protect animals from the most egregious forms of cruelty, what can we, as consumers, do? Opting out of paying someone to allow animals to die in a barn fire or at the slaughterhouse seems pretty reasonable.
